Patented June 16, 1936 Application May 7, 1935, Serial No. 20,301Renewed March 17, 1936 4 Claims.

This invention relates to a mechanical pinning device, the generalobject of the invention being to provide means whereby draperies,curtains and the like can be easily and quickly pinned to a table orbench without danger of the operator scratching his hand or the pinscatching in the goods when the device is in inoperative position.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of the device.

Figure 2 is a view looking through the rear edge thereof.

Figure 3 is an end view thereof.

Figure l is a front View View with the parts in lowered position.

Figure 5 is an end View with the parts in raised position.

Figure 6 is a bottom plan view with parts broken away.

In these drawings, the numeral l indicates an elongated beam and thenumeral 2 indiates a pair of aligned bars spaced from the front edge ofthe beam and hingedly connected thereto by the spring hin es 3, eachhinge having the leaf which is connected with the bar much longer thanthe leaf which is connected with the beamand the parts are arranged asshown in Figure 1 so that when the bar is lifted it will be aconsiderable distance above the beam. A pin carrying bar 3 is connectedby the hinges 5 to each bar 2, these hinges 5 being located under thebar. An arm 6 is connected to the outer end of each pin bar 3 andextends upwardly and a pair of brackets l extend upwardly from the rearpart of the beam adjacen the ends thereof and a link 8 has one endpivoted to the upper end of each arm 6 and its other end pivoted to theupper end of each bracket so that when a bar 2 is swung upwardly theseparts 6, 'l and 8 will cause the pin bar to swing downwardly andinwardly as shown in Figure 5.

Each bar l has the pins 9 extending from its lower face and these pinswill assume the position shown in Figure 5 when the parts are in raisedposition so that there is no danger of the operator injuring himself onthe pins. A plate Ii! is connected to the bottom of the beam l adjacentthe front edge thereof and extends outwardly beyond the beam and hasholes I l in its front edge for receiving the points of the pins whenthe pin bars are in lowered position as shown in Figures 4 and 6. Ofcourse, the material to be gripped is placed on the plate and then byswinging the bars downwardly the pins will grip and hold the same.

The bar 2 has a handle l2 connected thereto so that by swingin a handlerearwardly downwardly the bar 2 will be lifted, as shown in Figure 5,and a spring latch H3 is carried by the beam for holding each handle inlowered position with the bars in raised position. Thus when the handleis swung downwardly and rearwardly to raise a pair of bars the latchwill engage the handle and hold the parts in this position so that thelatch must be released before the parts can be swung downwardly in thegripping position.

A straight edge M is connected to the lower face of the beam and placedat one end of the device by a bracket I5, this straight edge acting tofacilitate placing of the device in position and the bottom of the beamis formed with a pair of grooves l6 which extend longitudinally and areout of alignment, the grooves extending from a substantially centrallyarranged recess I! in the bottom of the beam to the ends thereof wherethey communicate with notches l8 opening out through the bottom of thebeam and the straight edge is formed with a notch I9 which forms acontinuation of the notch l8. A bar 28 is slidably arranged in eachgroove and has its outer end bent downwardly as shown at 2! to form aclamp and this bent end carries a pin 22. A lever 23 extends into therecess I? and is pivoted to the beam as shown at 2 5 and a link 25connects the inner end of one bar 20 with the lever 23 at one side ofthe pivot 24 and a link 25 connects the inner end of the other bar tothe lever at the other side of the pivot as shown in Figure 6. A plate2? is fastened to the underside of the beam and covers the recess H andthe grooves, and the recess l'l extends through the rear edge of thebeam and the outer end of the lever 23 projects from the rear edge sothat it can be readily moved by hand. A yoke 23 has one end connectedwith the outer part of the lever and said yoke extends over a portion ofthe beam and then has its end bent and passed through a hole in the beamand said end forming the pivot 24. A spring latch 29 is carried by theupper face of the beam for engaging the yoke 28 for holding the parts inclamping position, it being understood that by moving the bars 20 inopposite direction to place the device on a table or the like and thenmoving the lever in an opposite direction the ends 2| will clamp thetable and thus firmly support the device thereon.

As it will be seen the bars 2 and 4 are of less thickness than the beamso that when the parts are in the position shown in Figure 3 the pins 9will act to hold an edge of the fabric in position. Then when it isdesired to release the fabric the handles l2 are swung downwardly underthe latches so as to raise the bars and thus the pins will disengage thefabric so that the fabric can be removed and the position taken by thepins, when the parts are in raised position will prevent the operatorfrom scratching his hands by the pins It is thought from the foregoingdescription that the advantages and novel features of the invention willbe readily apparent.

It is to be understood that changes may be :made in the constructionandin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

What is claimed is:-

1. A device of the class described comprising a beam, a bar, springhinges connecting the bar in spaced relation to the beam, 9. pincarrying bar, hinges connecting the same to the first mentioned bar, thehinges being connected to the lower faces of the two bars, a handle forswinging the first mentioned bar upon its hinges and means for swingingthe pin carrying bar downwardly to place the pins against the firstmentioned bar as the first mentioned bar is swung upwardly.

2. A device of the class described comprising a beam, a bar, springhinges connecting the bar in spaced relation to the beam, a pin carryingbar, hinges connecting the same to the first mentioned bar, the hingesbeing connected to the lower faces of the two bars, a handle forswinging the first mentioned bar upon its hinges and means for swingingthe pin carrying bar downwardly to place the pins against the firstmentioned bar as the first mentioned bar is swung upwardly, means forclamping the beam to a table and latch means for holding the handle inposition with the first mentioned bar in raised position.
